I was just going to say that there are many hardware parts in a computer. I would look at them or have a shop look at them before just throwing them away. Little things like:
-- Replacing the PSC
-- Is your RAM seated correctly
-- Video card -> big culprit
-- CPU
-- Motherboard
-- New drivers
It is much easier at a computer repair shop as they have a bench and can plug working parts in easily and see if it can be replaced.
It's kind of a gamble. Do I pay the minimum price of $70 or possibly $100 or do I just toss it?
I don't know much about laptops. Never owned one.
